About GrokStacks

GrokStacks is a searchable directory of the add-ons that make Grok Build, xAI's coding agent, more useful: plugins, agent skills and MCP connectors. Every listing shows what it contains and the exact install command from its own docs.

Where the data comes from

• 35 plugins from xAI's official Grok Build plugin marketplace (catalog and component index).
• 10 skills and connectors we hand-curated. Each install command is copied from the repo README or the Grok Build MCP docs.
• 286 plugins from Anthropic's official Claude Code marketplace, labelled Claude Code compatible. The Grok Build docs say Grok reads Claude Code marketplaces and plugins with no setup. We haven't tested these individually.

The data refreshes automatically every night. Listings last changed on 2026-10-16. No star counts, no fake reviews, and no "tested" badges unless we actually tested it.

Best lists

Our best Grok Build plugins pages are built from the catalog with a stated selection rule. They're not rankings and contain no paid placements.

Sponsor GrokStacks

Three ways to reach Grok Build users: a sponsor slot in the weekly email, a Featured listing at the top of the directory, or a category-page sponsorship. Sponsored and featured placements are always labelled. See the sponsor page for details and launch pricing, or email hello@grokstacks.com.
